It's hard to define this one, but what I have given Drupal is more users within a certain community: the Ubuntu Community.

I have contributed to awareness of the use of Drupal in our community using Drupal in several community sites and recommending its use to others. Also i have been tester for key components to achieve the ubiquity of Drupal in our community (Launchpad OpenID integration) and have pushed the boundaries of what Drupal can do for our community by making use of it in the SpreadUbuntu Project: Marketing for Human Beings!

Also I have contributed Drupal adaptations and theming on our move from Drupal 5 to 6 (through the Ubuntu-Drupal project) and also when Ubuntu moved to the new branding for community and commercial websites through my direct work with the Canonical designing team (I was involved because of my involvement in SpreadUbuntu).
